湿度的影响

Effect of Humidity

“干”与“湿”是以“相对湿度”来衡量的,“相对湿度”不完全在于空气中以气态形式存在的水的多少(“绝对湿度”),同时还要取决于温度,“绝对湿度”不变的情况下,温度升高,“相对湿度”就会下降。冬天气温低,不管是暖气还是空调采暖,相对湿度都会下降————干燥。干燥都会导致墨水容易使材料翘边,特别是PP纸,一不小心,就蹭喷头,严重的话会造成喷头和电机损坏。

"Dry" and "wet" are measured by "relative humidity". The "relative humidity" does not depend entirely on the amount of water (absolute humidity) in the air in the form of gaseous phase, but also depends on the temperature. When the "absolute humidity" remains unchanged, the temperature will rise and the "relative humidity" will decrease. In winter, the temperature is low, whether it is heating or air conditioning, the relative humidity will drop - dry. Drying will lead to ink easy to make material edge warping, especially PP paper, carelessly rubbing sprinkler, serious cases will cause sprinkler and motor damage.

温度的影响

Effect of Temperature

温度降低后,最常见的现象是喷头“假堵”,也就是个别喷嘴“断线”,因为同样的墨水,温度降低,黏度就会变大,粘度过大,在高速打印的时候就容易出现 “断线”,很多喷绘机用户会以为是喷头堵了,但是一经清洗,马上正常了,没有多久,又会重演,有客户又会认为是墨水质量问题。其次是墨水的吸收和干燥问题,温度过低,既不利于喷绘介质涂层对于墨水的吸收,也不利于墨水溶剂挥发。造成“堆墨”现象。

When the temperature decreases, the most common phenomenon is "false blockage" of nozzles, that is, "broken line" of individual nozzles. Because the same ink, the temperature decreases, the viscosity will become larger and the viscosity will be too high. When printing at high speed, it will easily appear "broken line". Many users of spray-painting machines will think that the nozzle is blocked, but after cleaning, horse. It's normal. It won't be long before it happens again. Some customers will think that ink quality is a problem. Secondly, the problem of ink absorption and drying is that too low temperature is not conducive to the absorption of ink by spray medium coating, nor to the volatilization of ink solvent. It causes the phenomenon of "ink pile up".

静电与灰尘的影响

The influence of static electricity and dust

相对湿度降低的另外结果,是静电和灰尘的增加。静电是造成电子产品烧毁的头等祸首,因为集成电路最怕静电。十年以前,当电脑还没有“飞入寻常百姓家”的时候,大部分是工作在电脑室中的,电脑室都要安装专门的防静电地板。如今,普通的室内环境,特别是使用空调,铺有地毯的情况下,冬季的静电特别容易烧坏电路板和喷绘机喷头。静电还会导致打印质量的降低,喷绘介质大都是“绝缘”的,喷绘机如果没有很好的防静电措施,或者没有接地线,喷出的膜滴就会因为静电的作用下,进一步附着到喷头表面,造成打印品质问题。

Another result of the decrease in relative humidity is an increase in static electricity and dust. Static electricity is the first cause of burnout of electronic products, because integrated circuits are most afraid of static electricity. Ten years ago, when computers were not "flying into ordinary people's homes", most of them were working in computer rooms, where special anti-static floors were installed. Nowadays, in ordinary indoor environment, especially when air conditioning is used and carpets are laid, the static electricity in winter is particularly easy to burn out circuit boards and spray nozzles. Static electricity will also lead to the reduction of printing quality, spray medium is mostly "insulated". If there is no good anti-static measures, or no grounding wire, spray film droplets will further adhere to the surface of the spray head because of the effect of static electricity, resulting in printing quality problems.
